Dairyland Power Cooperative (Dairyland) is a generation and Transmission cooperative based in La Crosse, Wisconsin that provides wholesale electrical energy to 25 member cooperatives and 20 municipalities who deliver the energy needs to over 500,000 people.

6 1 Dairyland's service area comprises 62 counties in Illinois, Iowa, Minnesota, and Wisconsin (Figure 1). Dairyland owns and operates over 3,000 miles of Transmission line , over 200 distribution and Transmission substations , numerous communication sites, and generation and utility properties. Dairyland is committed to the preservation and protection of precious natural resources. This best management practice (BMP) Manual and field guide were created in acknowledgement of that commitment. This Manual will provide Dairyland staff, consultants, and contractors with a comprehensive source for BMPs related to earth disturbing activities during construction , repair, and maintenance work associated with Transmission Lines , substations , and other cooperative projects.

7 The associated field guide is a water-proofed version of this Manual , which summarizes key erosion and sediment control points for use by field crews. Federal and state environmental permit information was also included in this document for reference. These practices and procedures, when properly implemented, will minimize or prevent erosion and sediment pollution from adversely affecting sensitive resources, such as, streams, ponds, lakes, wetlands, and natural vegetative. Erosion and sediment control measures are generally recognized as a necessary component of large construction projects.

8 It is equally important to note that those same measures apply to all earthmoving activity, regardless of size or scope. The smallest Transmission line repair activity could change water temperature in nearby trout streams or transport noxious weeds across property Lines if crucial Erosion and sediment control measures apply to all earth BMPs are not applied where required. BMPs are, in fact, moving activities small or large required in some form for all activities to preserve sensitive resources, regardless of the project size. This BMP Manual provides a comprehensive reference source for BMPs for construction activities and environmental compliance/permit policies and procedures.

9 This Manual must be periodically updated to reflect changes in BMPs in regulatory policy and in enforcement trends affecting and/or influencing the activities of Dairyland. 1.

Illinois Minnesota Dairyland Power Cooperative Service Area Iowa Wisconsin Introduction All individuals working on construction projects are responsible for complying with permit requirements and the associated BMPs as designed and detailed in this Manual and further specified by the Project Manager within site plans.

10 If questions arise concerning environmental requirements, the Project Manager should interpret compliance requirements. If the Project Manager is not available or able to resolve an issue, Dairyland's Manager, Siting and Regulatory Affairs should be notified. Some construction projects may require additional local environmental permits that could contain additional requirements that may be more restrictive than those identified in this Manual . Compliance with local permit requirements is mandatory. This Manual is presented in two volumes.
